Thanks to Dr. Sean aka Honus, B.A. (Barbarian Adventurer), for coining the name of this disease when explaining why Borriz the Dwarf couldn't accompany them on an adventure.
Dwarven Sprue, Respirator Agent; resisted by HT-2; 24 hour onset; 1 pt toxic damage, fatigue-based; cyclic (6 hour cycles, 12 cycles). Symptoms include fever, runny nose, sore throat, coughing, dizziness, and general fatigue (-1 to all attribute rolls) from start of onset; if victim is reduced to 1/3 FP or below, he or she also suffers from nausea (p. B428).
Dwarves are especially vulnerable to this disease, and resist at a further -2 (HT-4).
The Dwarven Sprue is easily diagnosed (+2 on Diagnosis rolls) due to fever and the characteristic discoloration of the skin (victims appear a little gray).
I seemed to have picked this up last week, or something like it. It hit me full-force on Sunday, forcing me to cancel game. I'm still shaking it off, but there is no way I'm passing up a chance to stat up the Dwarven Sprue for my game.
